background: clinically frank thyroid nodules are common and believed to be present in 4% to 10% of the adult population in the united states. in the current literature, fine needle aspiration biopsies are considered to be the milestone of a model which helps the physician decide whether a certain thyroid nodule needs a surgical approach or not. a considerable fact is that sensitivity and specif...

Noninvasive methods for the bacteriological diagnosis of early-stage Mycobacterium ulcerans infection are not available. It was recently shown that fine-needle aspiration (FNA) could be used for diagnosing M. ulcerans infection in ulcerative lesions. We report that FNA is an appropriate sampling method for diagnosing M. ulcerans infection in nonulcerative lesions.

Thymoma is a rare tumor derived from thymus epithelial cells and occurs mostly in patients between 40 and 60 years old with slight male predominance. Thymomas account for less than 1% of the human neoplasms. They are rare in children and young adults [1]. Fine needle aspiration cytology of thymic epithelial neoplasms remains an underutilized method of sampling mediastinal masses. A cytologic di...

OBJECTIVE To evaluate whether a preliminary aspiration (ASP) of the cystic component and/or using spinal needles in complex thyroid nodules (CTN) could improve the adequacy of cytological sampling. METHODS Between January 2004 and December 2006, 386 consecutive patients with CTN were enrolled in this prospective investigation. Ultrasound (US) fine needle aspiration cytology (FNAC) of the soli...

BACKGROUND AND STUDY AIMS Although Endoscopic Ultrasound (EUS)-guided tissue sampling is widely used, the optimal sampling strategy remains subject of debate. We evaluated practice patterns within the international endosonographic community. PATIENTS AND METHODS An online questionnaire was sent to 400 endosonographers from the United States, Europe, and Asia. RESULTS A total of 186 (47 %) e...

Background: Different types of endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) techniques are used in clinical practice; the best method in terms of outcome is not standardized. Objectives: To compare diagnostic adequacy of aspirated material, cytopathologic and EUS morphological features among capillary action, suction, and no suction FNA methods. Methods: A prospective, single...

OBJECTIVE Kikuchi-Fujimoto disease (KFD) is a self-limiting disorder which usually affects young women. There are only a few studies on pediatric KFD patients and their fine-needle aspiration (FNA) cytodiagnosis. We report a series of pediatric KFD patients diagnosed by FNA cytology and compare them with adults. MATERIALS AND METHODS By routine FNA cytology and through retrospective review sm...
